Three firsts! Jiufengshan Laboratory has made major breakthroughs in the field of compound semiconductors

Gallium nitride (GaN) is reshaping the rules of the game in the semiconductor industry. Recently, Jiufengshan Laboratory has achieved a series of breakthrough results from materials, devices to industrial applications.

In the clean room of Jiufengshan Laboratory, Wu Chang, chief expert in the wireless field of the research center, pointed to an 8-inch silicon-based nitrogen-polar gallium nitride substrate and introduced that the laboratory has made three disruptive innovations in the field of gallium nitride -
✅The world's first 8-inch silicon-based nitrogen-polar gallium nitride substrate,
✅The country's first 100nm high-performance gallium nitride wafer PDK platform,
✅20-meter long-distance wireless energy transmission technology, and in the future, science fiction scenes such as "second charging" for mobile phones, "charging while running" for electric vehicles, and "clairvoyance" for radar detection are accelerating into reality.

AMEC achieves major breakthrough in plasma etching technology

Advanced Micro-Semiconductor Equipment (Shanghai) Co., Ltd. (hereinafter referred to as "AMEC") announced that by continuously improving the accuracy of gas control between reaction tables, the ICP dual-reactor etcher Primo Twin-Star® has made new breakthroughs. The etching accuracy between the reaction tables has reached 0.2A (sub-angstrom level).

According to reports, this etching accuracy has been verified in the etching process of thin films such as silicon oxide, silicon nitride and polysilicon. This accuracy is approximately equal to one tenth of the diameter of a silicon atom of 2.5 angstroms, and one five millionth of the average diameter of a human hair of 100 microns .

In the repeatability test of 200 silicon wafers, the average etching speed of silicon oxide, silicon nitride and polysilicon test wafers on the left and right reaction tables of 100 wafers each differed by 0.9 angstroms, 1.5 angstroms and 1.0 angstroms per minute respectively. The difference in average etching speed between the two reaction tables (≤ 0.09%) is much smaller than the difference in etching speed of multiple wafers processed on one reaction table (≤ 0.9%).

AMEC revealed that the processing accuracy of CCP's dual-station Primo D-RIE® and Primo AD-RIE®, the etching repeatability of the two reaction tables and the repeatability on the production line have already reached the same level as Primo Twin-Star® . In the repeatability test of processing 1,000 wafers on each reaction table, the average etching speed difference between the two reaction tables was only 9 angstroms per minute, less than 1.0 nanometer.

A company out of nowhere debuting so many SME products.... How is this not the biggest news right now. AMAT LAM, KLA, TEL, Screen stocks will go on a nose dive in a few years. Same treatment WolfSpeed is getting right now.

Now I wanna know more and more details about SiCarrier. I know it involves Huawei and Shenzhen Government. But what happens when this company matures? Does it stay as Huawei subsidiary? Or become it's own independent company? Same concern for PST, PXW.

The amount of contributions a single company is having in single handedly leading China towards Semiconductor self sufficiency is just astonishing. They could have just laid low just like ZTE did after the sanctions. But their stubbornness got them to be written in history now. Just amazing
